The BSA Optix Hunting Series 4-12x40mm rifle scope with BDC-8 reticle is a straightforward, affordable optic built for hunters who need reliable magnification without the premium price tag. Designed for hunters running medium-power magnification in the field—whether you're glassing from a stand or taking a shot at moderate range—this scope balances a useful 4x to 12x zoom range with a 40mm objective that gathers enough light for dawn and dusk hunting. The fully multi-coated lenses maximize light transmission, a real advantage when low-light hours are often when game moves.
The BDC-8 reticle is engineered around common hunting cartridges, with holdover marks at 2, 4, and 6 MOA helping you dial holdovers for different distances without reaching for the turrets. If your shot requires elevation adjustment, the hand-turn turrets let you dial it in manually; the zero-reset feature lets you return to your starting point after adjusting for a specific distance. That's practical whether you're hunting multiple terrains in a single season or sharing a rifle between hunters with different zero preferences.
Built in black finish steel and ready to mount on Weaver rings, this is the kind of scope that works. It doesn't need Wi-Fi, a battery, or a ballistic calculator—just glass, coatings, and a proven reticle design. The fast-focus eyepiece keeps targets sharp without hunting for the sweet spot. For the hunter after a no-nonsense, mid-range hunting scope, the BSA Optix Hunting Series delivers.

Frequently Asked Questions
What hunting distances is this scope suited for?
The 4-12x magnification and BDC-8 reticle design make this scope a solid choice for hunters working at moderate ranges where a combination of light-gathering ability and field of view matters. The holdover marks on the reticle support practical hunting distances without needing constant turret adjustments.
Will this scope fit my rifle's mounting system?
This scope is compatible with Weaver-ring mounts, which are standard on most modern hunting rifles. Make sure your rifle's base is Weaver-compatible before purchase, or confirm your ring system matches the Weaver standard.
Does the fast-focus eyepiece require special adjustment?
The fast-focus eyepiece is designed for quick adjustments without special tools or calibration—you simply rotate it until your reticle appears sharp. Once dialed in, it stays put during normal hunting use.
What does the zero-reset turret feature do?
The zero-reset turrets allow you to adjust elevation for different distances, then return to your original zero point without guessing. This is useful if you adjust for a specific hunting scenario and want to quickly get back to your baseline zero.
